ECU Control Data Management
In order to prevent the misuse or illegal operation of an engine’s control system, the control program and
data are managed by a production system. In addition, Yanmar’s production data management system can
provide the correct data for replacing an ECU and / or fuel injection pump when it is necessary.
ECU Control Data Management In Factory
The flow of ECU control data management in the factory is shown in
Figure 6-51
. Control program, data
map and data are assigned to a part number for each engine model. Engine production data and adjustment
data are specific for each engine and injection pump. The ECU control data for each engine is stored in the
factory server after running tests in the factory.
